NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed March 24, 1906. Serial No. 307,820.

To all whom it may concern.-

Be it known that I, SAMUELR. HARRIS, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Non-Refillable Bottles, of which the following is a specification.

My invention has relation to a non-refill able bottle; and in suchconnection it relates more particularly to the construction andarrangement of a stopper which when a common stopper is removed from thebottle permits of the outflow of the contents of the same, but preventsthe refilling of the bottle.

The principal objects of my invention are, first, to provide abottle-stopper with a valve to support the same therein so that thevalve can only be opened by a pressure brought to bear against the valvefrom the interior of the bottle; second, to provide the stopper with ayielding covering which when the same is driven into the neck of thebottle and is thus compressed offers sufficient resistance to hold thestopper in the position given to resist displacement or removal of thesame from the neck; third, to form the stopper of a sectionalcylindrical housing and to close the open end thereof by a valve whichis held on its seat by a spring irrespective of the po sition the bottlemay occupy when the same is empty, but which readily permits the outflowof the contents of the bottle up to the last portion thereof, and,fourth, to provide the housing outside the seat for the valve with acontracted portion forming a chamber and a should er which limits themovement of the valve when abutting therewith to prevent outflowingliquid passing through openings arranged in the end of the housing, butadmitting the passage of liquid therethrough when the bottle isattempted to be refilled.

The nature and scope of my invention will be more fully understood fromthe following description, taken in connection with the accompanyingdrawings, forming part hereof, in which Figure 1 is a view illustrating,partly in section and partly in elevation, the upper portion and neck ofa bottle, with a stopper arranged in the neck embodying main features ofmy said invention. Fig. 2 is a view illustrating in elevation thestopper prior to its introduction into the neck of the bottle and theyielding ferrule projecting beyond the stopper; and Fig. 3 is a viewillustrating,

partially in section and partially in elevation, the several parts ofthe stopper discon nected from each other.

Referring to the drawings, a represents a bottle provided with a neck a,the interior channel a of which is circular and of uniform diameterthroughout to permit of the insertion of a metal stopper b thereinwithout breaking the neck during the insertion of the same. Thestopper 1) is inserted in the neck a of the bottle a after the same hasbeen filled with liquid, and the insertion of the stopper may beaccomplished prior to the introduction and closing of the bottle by acommon stopper, (not shown,) or this common stopper when driven into theneck a by hand or machinery may be utilized to drive the stopper 6 intothe neck a in the position shown in Fig. 1, for which purpose thestopper 1) may be partially inserted into the neck in advance of thecommon stopper.

In order to hold the stopper b in the neck a 1n the position given bythe insertion of the common stopper, (not shown,) the housing 1) thereofis provided with a ferrule c, preferably consisting of cork. As shown inFigs. 2 and 3, the ferrule c in its normal condition extends slightlybeyond the housing I), so as to permit of-a compression of the same whenthe stopper 1) is inserted in the neck a of the bottle a, and thusproduce the necessary friction between the neck and stopper to hold thesame securely in position in the neck. A shoulder b preferably formedintegral with the housing 1), serves to prevent displacement of theferrule c thereon and also forms a support for a cap I)", which fitsover the end 6 of the housing I), as shown in Fig. 1. The end 5 isprovided with an inclined surface b which forms a seat for a valve d,having a range of sliding movement within the housing b and cap I) andresting with its tapering portion (1 upon the inclined surface 5 thusforming a liquid-tight closure. The interior of the cap b at its end isof less diameter to form a chamber 1) and a shoulder 1), against whichthe valve (1 abuts when the same is raised from its seat I) by liquidflowing from the bottle held in a tilted posit-ion. In this instance theliquid passes through a series of openings b arranged between the seat band shoulder b", and enters a chamber a formed by the cap b and the necka of the bottle a, and flows from thence through the neck a into areceptacle placed beneath the same. By the abutting of the valve 61against the IlO shoulder]; the liquid is prevented from entering thechamber b and passing through openings b arranged in the end of the capI). By preventing the outflow of liquid through the openings 11 thecollection of sediment above the valve (1 is prevented, and by stoppingthe valve short of the openings 1) it insures action upon the uppersurface of the valve of any liquid entering the openings b". In thechamber b and housing I) is arranged a spring e, which bears with oneend against the cap 17 and with the other end against the valve (1, asshown in Fig. 1. This spring 6 is sufficiently strong to support thevalve d when the bottle a is tilted or is held with its neck a downwardin a vertical position. As long as liquid remains in the bottle a thesame will readily overcome the force of the spring 6, open the valve (1,and leave the bottle through the openings 6 of the stopper 6. If,however, no liquid remains in the bottle a, the valve (1 will be held onits seat I) by the spring e, and any attempt to refill the bottle a in atilted or upside-down position will thus be effectually prevented. Onthe other hand, if a refilling of the bottle a is attempted when thesame is yet partially filled in order to overcome the force of thespring 6, and thus keeping the valve d open, the li uid entering in'thisinstance the stopper 1) st through the openings 19 will assist thespring 6 in the closing of the valve (1, and thus also prevent therefilling of the bottle in such a position.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a non-refillable bottle, a stopper consisting of a housing havinga seat, a cap having superposed openings and a shoulder forming a seat,secured thereto, a valve arranged within said housing and cap andadapted to slide between the seats thereof, a spring ar ranged in saidcap and adapted to hold said valve on said housing-seat in the normalpo- 4 5 having a seat and superposed openings arranged on both sidesthereof, said cap secured to said housing, avalve arranged in saidhousing and cap and adapted to slide between the seats thereof, a springarranged in said cap and adapted to hold said valve on said housing-seatin the normal position of the bottle and when empty or tilted, and theseat of said cap arranged to prevent outflow of liquid through the upperrow of openings when said valve is forced downward by the liquid againstthe tension of said spring.

3. In a non-refillable bottle, a stopper, consisting of a housing havinga seat, a cap having a seat and superposed openings arranged on bothsides thereof, said cap secured to said housing, a valve arranged insaid housing and cap and adapted to slide between the seats thereof, aspring arranged in said cap and adapted to hold said valve on saidhousing-seat in the normal position of the bottle and when empty ortilted, and the seat of said cap arranged to prevent outflow of liquidthrough the upper row of openings when said valve is forced downward bythe liquid against the tension of said spring, and means secured to saidhousing adapted to hold said stopper, by friction, in the neck of saidbottle.

In testimony whereof I have hereunto set my signature in the presence oftwo subscribing witnesses.
